Selected License

The "Selected License" panel displays information about the license
that was described in the "License Features" panel. Changing the values in the
"License Features" panel will update the information displayed here.

Approved for Free Cultural Works

If the selected license provides the freedoms required of a free culture license,
then the "Approved for Free Cultural Works" icon appears on this panel. This
feature is intended to assist you in making a more informed decision.
NonCommercial and NoDerivatives licenses include additional restrictions
which, by definition, prevent them from being considered free culture licenses.

While our non-free culture licenses are useful in particular circumstances, unintended
consequences may result from their use (such as license incompatibility).
For example, a work that is under the license "Attribution-NonCommercial-ShareAlike"
may not be combined with a work licensed "Attribution-ShareAlike" because putting
the resulting work under either license violates the other by either
adding or removing the NonCommercial restriction.

A real world example of license incompatibility: Works with the NonCommercial
or the NoDerivatives restriction may not be posted to Wikipedia.

Have a web page?

The HTML provided in this panel may be pasted into your website to display which license applies to your work, as well as attribution information. The HTML combines information provided in the "License Features" panel and the "Help others attribute you!" panel. The HTML also contains RDFa metadata, which allows search engines to accurately determine which license your work is under, and how you want to be attributed.

This panel also contains a preview of what the HTML will look like when included in your website. The radio buttons at the bottom of the panel may be used to change the size and appearance of the license icon in the HTML.
